PROCESS OF PRINTING.

SPECIFICATION forming part of Letters Patent N o. 722,591, dated March 1U, 1903.

Application ned November 17, 1902.

.To all whom, it may concern:

Be it known that we, RUFUs J. KITTREDGE and JACQUE NIEMES, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Process of Printing, of which the followingis afull, clear, and exact specification.

Our invention relates more particularly to the art of printing dierent colors or eects upon the same sheet, and the improvements have especial reference to the method of preparing the sheet for the application of bronze, gilt, or other similar material.

The primary object of the invention is to avoid the necessity of printing the sheet with size for causing the bronze or gilt to adhere and to so lay on the different colors or coats as to make the bronze or -gilt stick in the desired places without the employment of other adhesive. Y

More specifically stated, the object of our invention is to cause the colors or inks to overlap where the bronze or gilt is to be applied, so that these places will remain tacky or sticky after the other surfaces are dry, and consequently will receive and retain the bronze or gilt in exclusion of the dry surfaces.

With these endsin view our invention consists in certain features of novelty hereinafter described with reference to the accompanying drawings and more particularly point:v ed out in the claims.

In the said drawings, Figure lis adiagram. matic illustration of a sheet of paper or other material, showing the first step of the process. Fig. 2 is a similar view illustrating the 'seclond step or the overlapping of the colors or inks. Fig. 3 is a similar view illustrating the third step or the application of the bronze or gilt to the overlapped inks or colors, and Fig. 4 is a theoretical or exaggerated cross-section of the finished sheet.

In carrying out our invention we print the sheet with the Various colors in the usual or any suitable way; but the plate for one of the impressions is larger than the other or others, so that the impression produced thereby will overlap at least one of the impressions produced by the other plate or plates, and consequently make the ink thicker in some Serin No. 131,654. (No specimens.)

places than in others, thesethicker places being where the second color overlaps the first. Consequently if the sheet be thereafter allowed to stand until the single thicknesses of ink are dry the double thicknesses will still be sufficiently tacky or green to receive and I hold the bronze, gilt, or other dried material that may be employed in this art for the purpose of producing a bronzed or like effect.

In the drawings we have illustrated a sheet which isl printed with two colors or impressions and a coating of bronze incertain places; but it will nevertheless be understood that this is a mere example of the invention and that any desired number of colors or impressions may be produced and subsequently bronzed in certain places according to the same principle. In this example it will be observed that the figures or representations of the two lions, the crown, and the scrollwork are produced in gilt, while the background is produced in one color and the space inclosed by the scrollwork in a different color. In producing this eect the sheet is first printed, as indicated in Fig. 1, in which the first color or background color 2 is carried inwardly into the inner line of the scrollwork, the spaces 1 being the plain or unprinted paper. The next impression 4, which produces the outer line of the scroll, crown, and the lions, islaid on from the inner line 2a of the background color outwardly, overlapping the background color 2, and thereby producing a double thickness or coat of ink in the places representing the said figures, crown, and scroll. VIf now the sheet be allowed to remain until the two single colors 2 3 are dry, the overlap 4; will still be moist or tacky, and if the sheet be then dusted with bronze or any other powder or similar substance, or if gold-leaf be applied thereto, the same will stick to the overlap 4 and will readily brush off the single thicknesses 2 3, leaving a third coat 5 of bronze, gilt, or powder. By this method it will be seen that perfectly sharp outlines of gilt Aor bronze may be produced wherever desired, a'result which is practically impossible of production according to the-prior method of printing the sheet with size in the places where is is desired to produce the bronze effect because of the great diiiiculty in getting the size-printing plate to ICO by Letters Patent, is-

1. The hereindescrihed process of printing which consists in applying a pluralit7 of colors to the same sheet With one color overlapping a previously-applied color, allowing the colors to dry excepting Where overlapped and then applying the bronze to the overlapped portions, substantially as set forth.

2. The herein-described process of printing which consists in applying a plurality of colors to the same sheet with one impression overlapping a previously-applied color before the latter is dry, allowing the colors to dry excepting where overlapped and then applying bronze to the overlapped portions, substantially as set forth.
